Abstract：Motion perception is one of the important parts of the mind mechanism of biological vision. Based on the fundamental principle of Formotion BCS

and combined with monocular boundary perception processing

this thesis develops a monocular neural dynamic model of motion direction detection. It is different from the Formotion BCS that the mechanism of asymmetrical direction detection is expanded at transient network processing stage

inhibition kernel in the reverse direction is taken at the competition network processing stage and the cooperation mechanism of the motion bipole cells is taken at the boundary segmentation processing stage in the model. We have simulated it on the computer successfully. The model helps us to realize a motion direction detection system based on biovision theory that is different from those normal models in the field of computer vision.
